Add support for building modules from preprocessed source.
To support this, an optional marker "#pragma clang module contents" is
recognized in module map files, and the rest of the module map file from that
point onwards is treated as the source of the module. Preprocessing a module
map produces the input module followed by the marker and then the preprocessed
contents of the module.
Ignoring line markers, a preprocessed module might look like this:
module A {
header "a.h"
}
#pragma clang module contents
#pragma clang module begin A
// ... a.h ...
#pragma clang module end
The preprocessed output generates line markers, which are not accepted by the
module map parser, so -x c++-module-map-cpp-output should be used to compile
such outputs.
A couple of major parts do not work yet:
1) The files that are listed in the module map must exist on disk, in order to
build the on-disk header -> module lookup table in the PCM file. To fix
this, we need the preprocessed output to track the file size and other stat
information we might use to build the lookup table.
2) Declaration ownership semantics don't work properly yet, since mapping from
a source location to a module relies on mapping from FileIDs to modules,
which we can't do if module transitions can occur in the middle of a file.

[scudo] Add Android support
Summary:
This change adds Android support to the allocator (but doesn't yet enable it in
the cmake config), and should be the last fragment of the rewritten change
D31947.
Android has more memory constraints than other platforms, so the idea of a
unique context per thread would not have worked. The alternative chosen is to
allocate a set of contexts based on the number of cores on the machine, and
share those contexts within the threads. Contexts can be dynamically reassigned
to threads to prevent contention, based on a scheme suggested by @dvyuokv in
the initial review.
Additionally, given that Android doesn't support ELF TLS (only emutls for now),
we use the TSan TLS slot to make things faster: Scudo is mutually exclusive
with other sanitizers so this shouldn't cause any problem.
An additional change made here, is replacing `thread_local` by `THREADLOCAL`
and using the initial-exec thread model in the non-Android version to prevent
extraneous weak definition and checks on the relevant variables.

Fix handling of signWrappedSets in access relations
Since r294891, in MemoryAccess::computeBoundsOnAccessRelation(), we skip
manually bounding the access relation in case the parameter of the load
instruction is already a wrapped set. Later on we assume that the lower
bound on the set is always smaller or equal to the upper bound on the
set. Bug 32715 manages to construct a sign wrapped set, in which case
the assertion does not necessarily hold. Fix this by handling a sign
wrapped set similar to a normal wrapped set, that is skipping the
computation.

Fix segfault resulting from empty print prompt
Summary:
I have found a way to segfault lldb in 7 keystrokes! Steps to reproduce:
1) Launch lldb
2) Type `print` and hit enter. lldb will now prompt you to type a list of
expressions, followed by an empty line.
3) Hit enter, indicating the end of your input.
4) Segfault!
After some investigation, I've found the issue in Host/common/Editline.cpp.
Editline::MoveCursor() relies on m_input_lines not being empty when the `to`
argument is CursorPosition::BlockEnd. This scenario, as far as I can tell,
occurs in one specific instance: In Editline::EndOrAddLineCommand() when the
list of lines being processed contains exactly one string (""). Meeting this
condition is fairly simple, I have posted steps to reproduce above.

ABISysV_arm64: compute return value for large vectors correctly
Summary:
Arm64 Procedure Call Standard specifies than only vectors up to 16 bytes
are stored in v0 (which makes sense, as that's the size of the
register). 32-byte vector types are passed as regular structs via x8
pointer. Treat them as such.
This fixes TestReturnValue for arm64-clang. I also split the test case
into two so I can avoid the if(gcc) line, and annotate each test
instead. (It seems the vector type tests fail with gcc only when
targetting x86 arches).
